These pics are kinda crappy but so is my camera sooo....

The 1st pic shows the floating hatcher I first used. I now use this for the 1st 12 hrs to sort out the viable and non viable eggs( dead eggs sink). The eggs hatch 12-15 hrs at 80-82 degrees.

2nd pic shows the "windows" in the sides of the floating hatcher.

3rd pic shows the closed loop system I use to provide some flow in the containers.

4th pic is a down shot of the inside of the acrylic floating container. The pro-larval and larval fish are difficult to impossible to spot right now. You have to use a strong flash light from the side at several different angles.

Additional note: Larval form floats in all levels of the container head down. Newly hatched pro-larva float near/at the top. The drip line provides a slow current for the larval fish. I've added algae, copepods and rotifers to the container. More on this to follow in other posts.
